Buying New Tires
To find out what kind and size of tires your vehicle
needs, look at the tire and loading information label. For
more information about this label and its location on
your vehicle, see Loading Your Vehicle on page4-29.
Thetires installed on your vehicle when it was new had a
TirePerformance Criteria Specification (TPC Spec)
numberon each tire’s sidewall. When you get new tires,
GMrecommends that you get tires with that same TPC
Specnumber. That way your vehicle will continue to have
tiresthat are designed to give proper endurance,
handling,speed rating, load range, traction, ride and
otherthings during normal service on your vehicle. If your
tireshave an all-season tread design, the TPC number
willbe followed by an “MS” (for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels. It’s all right to drive with your
compact spare temporarily, it was developed
for use on your vehicle. See Compact Spare
Tire on page5-85.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.
